AUTQMATIC LUBRICATING BEVI'G'E.

To all wwm ii may conccrn:

Be it known that I, O'i'x'o WINiuinn, a subject of the Kin'g of Prussia, residingv at K' enick, Germany, have made certain new o an usefull mprovements in Automatic Ifubricating Devices, of which the follow in' -is a speeification.

lhe piesent invention relates to automatic luhrieating devices and has for itsl object to improve and simp ify their construction.

For consideration of what I believe to be novel and my invention, attention is directed to the accompanying specification and the claims appended thereto.`

the accompanying drawing is shown one of the ernbodiments of my invention as applied to an internal cornbustion engine.

l indi'cates the cylinder of an 'internal `:ombustion engine'and 2 the piston thereof.

2G The piston is connected by a rod 3 with the Crank 4, the letter being located i'n a closed Crank case 5.

6 indicates the main/shaft of the engine that is supported in suitable bearings 7 of 2.5 whiain one 1s shown.

E indicates the admissio valve and S) the String device.

The combustible mixture is supplied to the engine by the conduit 10. Attached to the conduit is a Venturi tube ll, the letter forming a inixing tube or mixing nozzle. (asolene or other fuel is admitted to the tube from the chamber 12 by the small n02 zle .13. 3b the adrnission valve 8 being open, a suelion is created in the Ventui'i tube. This sur'lion oeuses the fuel from the Chamber entrained with the air.

lt indieates a closed vess'el of any suitable contruelion to which connected a section pipe 15, the lattcr opening into the f Venturi tuhe 11 at a point Where the veloc ity of the air is r- 'lat,ively high. 'ilu'v .fiir as it tlow through the tube cau.of\ a `auction in the pipe 1:3.

"n the Vssel 14 is :i float valve 16 that is arz'anged to engage its sent 17 and close the entrance to the auction pipe 1.3 when the level of the luhricant in the Chamber Mt needs a certain amount.

To the under side of the Yossct is con neclefl the lnhricnnt Parrying tube 18. the lower eniil ot which is inimersed in the i' luhriezint ms'rltained in the reservoir M5v indivalee a manifold that i connected On the down stroke of the piston`y to and recei'res lnbrieant from the vsel 14. To the manitold are connected pipes vthat lead to the various bearings on the engine or they may lead to the auxiliary devicesv that are driven by the engine and requiro such lubrieation.

The operation is as follows: A8 the piston moves down, the value 8 being open, a auc` tion is created in the tube 15 and `veseel 14 which suche lubricant from the reservoir l9. The lubricant thus raised is delivered by the manifold 20 and the nipes 21 to the various bearings. The valve 16 is so arranged that it prevents lubricant from being sucked through the tube 15 into the Venturi tube ll. It will thus be seen that as soon as the engine starts the luhricating system starts into operation and stops as soon as the engine stops. i

My i'nvention is also applicable where the parts to be lubricated are located above the level of the lubrioant in the reservoir ,1.9 because the sucking of .air through the manifold and pipes 21 will be Prevented by the auction action of the bearings and by the capillary attraction of the oil in the bearinga By returning the lubricant from the bearings to the reservoir 19 When the latter is located below the level of the bearings the invention is applicablo to an automatic cir culation.

In :rccordnnce With the 'provisions of the i patent statules, l have dcscribed the prinoiple of operation of my invention, together with the apparatus which I now oonsider to represent the best ernbodiment theroof; hut l (leev to have it understood that. the apparatus shown is only illustrative, and that the invention cen bo carried out by other means.

1What l claim new and rlesire to secure by Lettera ,Patent of the United States tl. An internal oon'ihustion engine having a fucl inlet oonduit in combination with a luhriennl containlng vessel connected there to and suhjccted to the suction effects existing in the con'luil., a valve for preventing luhrimnt. from entering the conduit from the vessel, and :i discharge pipe that 'receives its supply of luhricant 'rom the vessel.

2. in combination a conduit in which a su-etion is created, a. chainbered versel con neclod to the conduit and suhjected to the auction eilecte existing therein, a i'e'fex'voir from whieh lubricant is raised to the vessel,

a valve preveflting iuhricant from ffowing from the veesel` to said conduit, and one 01' more pipeV (zon'feyng4 ubreant from the vesse to the parts to be lubricated.

3. In combination, a conduit in which eV v '4. In eombinationyagconduit in which a suctioniis created by a moving machine part,

a.. .closed chembered vesse' which is subfi jecteilto the suetion efi'ects' existing in the eonduit, e? flat, valve in the "veesel that is edapte'd to. close the cemmunication between the vessel end the conduit when the fluid therein -reaches a' certen level, e reserveir.

ownward from the vessel vhose lower end is submerged m lubrlcmit m the reservoir,

an nieans for supplyng lubricent fi'em the pipe connected et oneen'd to the tube and at the other end to the Vessel a fieet vel've in the vessel thet eontrols the auction ipe,

ta pipe that freelfy diseharges lubricant ram the vessel, a hlhx'icant tube that disc'mrgesr into thev vessel, and a reservoir containing hlhrcant into which the lubrieant tube ex; tends.

In witnese -whereof, l have hereunto set myhand. A
